ASUS EAH3450 HDMI work on OPENSUSE 11 now.

I bought a ASUS EAH3450 HDMI video card, but HDMI port not work at first.
My computer motherboard is M2A-VM, OS is OPENSUSE 11.
I have download the latest driver from ATI, useless.
Found there new version (2201) bios at ASUS website, download it, update it,lost verything; computer crashed.
After Google, remove this video card, remove battery from motherboard,wait few minutes, put battery back, vidoe come out from motherboard VGA port.
Put everything back, setup bios to PCIe video card, and HDMI work for me!!!
